11 Claims. (Cl. 223-76) 'I'his invention relates to apparatus for treating textiles which are capable of being set.

More particularly, this invention relates to ap-Y addition to having a desirable finish, an even-#'45 ness of sheen, and a soft touch, be free of any I' creases or wrinkles. Heretofore, wrinkle-free hosiery could be obtained by subjecting the ar-'" ticle, as a final processing step, to a boarding treatment. This, in most instances, consisted ofy positioning the hosiery in a moist condition on shaping boards under tension and drying same. The dryingsets the hosiery to the shape ofy the board and is accomplished by either internally heating the shaping board or by applying heat externally to the hosiery. Textile articles composed of natural silk or artificial cellulosic flbers, when subjected to such a treatment, were freed from wrinkles and creases caused by the dyeing and other preceding process steps, andthe articles exhibited an excellent appearance for sales purposes. l

The sequence of operations in the previously known commercial manufacture of hosiery com.-

. to dye hosiery composed of natural silk or artificial cellulosic fibers or filaments, it is necessary toA subject them to a hot-wet treatment. During this and the preceding operations, the stockings will, in all probability, be creased or wrinkled. subjecting creased or wrinkled hosiery composed of natural silk or artificial cellulosicebers or filaments to the hot-wet treatment necessary for dyeing does not permanently set the creases or wrinkles therein, and such creases or wrinkles that occur during this and the preceding operations will be removed therefrom by the subsequent boarding operation.

However, inthe treatment of products knit from threads composed of synthetic filaments or fibers, such for example as synthetic linear polyamides, the prior art methods hereinbefore described cannot be employed commercially. Knit products comprising synthetic linear polyamides once creased or wrinkled prior to or during a hot wet treatment that the creases or wrinkles present in such products will be removed therefrom. Such extremely long and drastic treating steps are most uneconomical. and when employed, increase the cost of the nished product.

It has been discovered that textiles, such as stocking, comprising filaments or fibers of synthetic linear polyamides should preferably be set before any creases or wrinkles are present therein. Such a set may be obtained by subjecting wrinkle-free hosiery positioned on a form, board, or the like under tension to a hot-wet treatment. Textile products comprising synthetic linear polyamides so treated will remain free from permanent or semi-permanent wrinkles or creases, even though subsequently subjected to the conventional hot-wet dyeing operation.

This invention has as an object a new apparatus for treating textile products which are capable of being set. A further object is a new apparatus for setting knit textile products comprising synthetic fiber or filaments which are capable of being set. A still further object is a new apparatus for setting textile products comprising fibers or filaments of synthetic linear polyamides. Another object is a new apparatus for preventing the formation of permanent creases or wrinkles in knit textile products comprising synthetic bers and filaments. Another object of this invention is a new apparatus for preventing the formation of permanent creases or wrinkles in knit textile vproducts comprising synthetic filaments or fibers, such for example as synthetic linear polyamides. Another object is a new apparatus for setting a plurality of textile products comprising synthetic filaments or fibers simultaneously. A still further object is a new apparatus for setting a plurality of stockings comprising synthetic linear polyamides simultaneously. Other objects will appear hereinafter.

These objects are accomplished in the present invention by the discovery of a new and improved board-setting apparatus.

The invention fully comprehends the foregoing and other objects all of which will be explained in detail and more readily understood when read in conjunction with the accompanying drawings which illustrate one practical embodiment thereof; it being therefore obvious that other arrangements and applications of the invention may be resorted to Without departing from |the spirit and scope of the concluding claims.

Cil

Referring more in detail to the drawings, one

invention, the tracks are fastened to the top of the supporting base by bolts 24 (Fig.,2) and lock washers 25 Fastened to the rear end of the supporting base is a bumper ysupport 26, and attached to the bumper support are bumpers 21.

'I'he head end of the supporting base has attached thereto a mounting plate shaft support (Figs. 2 and 5). said member supporting the weight of the rotating mounting plate and the parts attached thereto.

Tank 2| is horizontally movable on tracks 23 by means of wheels 3| (Figs. 2, 3, vand 5), said wheels being fastened to the underside of the tank by tank pillow block supports 32 (Fig. 3), tank pillow blocks 33, and axles 34 and 35 (Fig. 2). The flanges of the Wheels 3| fit over the tracks ,23 and prevent the tank from becoming derailed. Bumper support 26.(Fig. 2) and bumpers 21 prevent the tank from rolling off the tracks at the rearrend of the supporting base. Wheels 3| are attached to the axles 34 and 35 by pins 36 and are made to rotate therewith. The rear end axle 35 is made longer than the headend axle and has attached thereto, at one end, a sprocket 31 (Figs. 1 and 3), said sprocket being attached to said axle b y a sprocket pin so that both axle and sprocket rotate together.

The rear end of tank 2| is provided with a circular head plate 4| (Fig. 4 for enlarged detail), the diameter of which is substantially the same as the inside diameter of the tank. This plate is fitted into the cylindrical shell of the tank substantially close to the end and is welded thereto so that it forms a pressure-tight joint between the cylindrical shell of the tank and the rear end plate. Welded to the plate 4| are a retainer support 42 and reinforcing ribs 43.

The head end of the tank 2| is provided with a head plate 44 (Fig. 4 for enlarged detail), said A plate being circular and substantially larger in diameter than the outside diameter of the cylinthe end of the tank and has a rectangular open- ,v

ing 45 cut therein. A gasket 46 is fastened to the head plate around the opening 45 and provides a means for forming a tight joint between the movaigle tank 2| and one face of the mounting plate 2 Circular hollow tubes 41 (Fig. 4), the length of which are substantially the same as the length of the tank 2|, are fitted into the tank. These tubes are in the same vertical plane and are supported at their ends by plates 4| and 44. Locking bars 50 (Figs. 4 and '1), substantially longer than the tubes, are placed therein. Bushings 5| (Fig. 4) are fitted inside the tubes 41 and provide a support for the locking bars 50. The outside diameter of the locking bars is substantially smaller than the inside diameter of the bushings so that the bushings may slide thereon. This construction enables the tank 2| to move in a horizontal direction along the locking bars 50. One end of the locking bar (Fig. '7) has a shoulder 52 and thread 53 cut thereon, while the other end is flattened at the top and bottom and has fastened thereto, by means of a heavy force t through the flattened section, a locking pin 54.

The setting agent for treating the products while positioned inside of the tank is admitted into the tank through an inlet connection 55 (Fig. 2) and is exhausted therefrom at the outlet connection 56 by means of hand valve 51 and discharge drain 60. In order to facilitate the heating of the inside of the tank 2| so as to speed up the treating operation, a heating element, such for example as steam coils, may be installed therein. Temperature and pressure recorders for the tank are provided at connections 6| and 62 (Fig. 1).

In order to admit the stocking forms or boards into the inside of the tank for treatment and remove same therefrom after the setting operation is completed, it is necessary to have the tank readily movable. Such movement takes place, in the present embodiment of this invention, on tracks ,23 and is provided by handwheel 63 (Figs. 1 and 3), said wheel being connected to a vhandwheel shaft 64 and made to rotate therewith. A sprocket 65v is attached rigidly to one end of the shaft 64 so that both sprocket and shaft rotate together. Shaft 64 is supported in shaft pillow blocks 66, said pillow blocks being attached to shaft pillow block supports 61 which are in-turn welded to the top of tank 2|. Sprocket 65 isin the same vertical plane as sprocket 31 and is made to rotate therewith by the travel of asprocket chain 1|. 1

In order to lock the mounting plate 22 to the movable tank 2|. a. locking device is provided. This mechanism consists of locking hooks 12 (Figs. 2, 4, and 5) which are fastened to a mounting plate shaft 13.'said hooks being attached to said shaft by pins 14 so that the locking hooks rotate with the mounting plate shaft 13. The mounting plate is supported by and rotates in pillow blocks 15 (Figs. 2 and 5), said pillow blocks being fastened to the mounting plate shaft support 36. Rotation of the mounting plate shaft is obtained by means of a remote control mechanism. This mechanism is shown in detail in Fig. 8 and consists of a support 16 fastened to the supporting base 20 at any convenient location, a pivot pin 11, a control lever 80, a control lever pin 8|, a mounting plate shaft bushing 82, a mounting plate shaft bushing pin 63, and a connecting rod 64. The mounting plate shaft bushing 82 is rigidly attached to the mounting plate shaft 13 by pins 00 and is further provided with an adjustable stop 00. When the control lever is moved horizontally about the pivot pin 11, the remote control mechanism causes the mounting plate shaft 13 to turn in the pillow blocks 15, and as this shaft rotates, the locking hooks 12 rigidly fastened thereto, also rotate. In order to lock the tank 2| to the mounting plate 22, the tank is-moved horizontally along tracks 23 by means of handwheel 03 until the locking pins 54 in the locking bars 50 are substantially in line with the locking hooks 12. Movement of the control lever 00 causes the locking hooks 12 to become engaged around the locking pins, thussecurely holding the tank in place. In order to provide a tight connection between the head end of the tank 2| and one of the faces of the mounting plate 22 so that superatmospheric pressure .may be maintained in the tank, a final adjust- ;nent is provided. This adjustment, in the presjant embodimentV of this invention, is shown in @detail in Fig. 4 at the rear end of the tank and comprises a beam 01, a screw 90 and 'a handv.Wheel 0|. v f The beam 31 is attached to the rear end of fthe locking bars 50, said beam being-rigidly attached thereto by lock washers 92 and nuts'03. a

v"A bushing support 04 is fastened to the beam 81` substantially in the center thereof, and fitted into thebushing support isa threaded bushing 95. The threads on the screw 90 t 4into and cooperate with the thread in the bushing 95. One end of the screw 90 has the handwheel 3| attached thereto so that any rotation of the handfavheel causes rotation of the screw. The head end of the'screw has fitted thereon the inner-race of a ball bearing 00. The outer race of saidball :bearing is fitted to a ball bearing retainer 91, said retainer being attached to the retainer support 42 by bolts 90. Final adjustment for maintaining pressure in the tank is obtained by rotating handwheel 0|. This causes the tank 2| to slide along the locking bars 50 and forces a tight joint between the gasket 46 and the face of the mounting plate 22.

In order that the cycle of operation for treating the textile products may be economically carried out, a mounting plate with three equal faces, each face supporting 20 stocking forms or boards, is provided. This gives the operator time to load and remove the treated stockings during the treating period so that one operator is continuously kept busy. Such a procedure necessitates a readily rotatable mounting plate. This movement is accomplished'in the present embodi` ment by the rotation of the mounting plate 22 about the mounting plate shaft 13 (Fig. 4) on multi-roller bearing 99 and ball bearing |00. The

inner race of the ball bearing |00 is attached to` bushing |0| which is in turn fitted onto the mounting plate shaft 13, while the outer race of the bearing is tted onto the mounting plate 22. These bearings are provided with oil retainers |02.

Attached to each face of the mounting plate 22 is a mounting plate base |03 (Figs. 4 and 9), said base being attached thereto by means of mounting plate bolts |04 which engage in mounting plate bolt holes 04a (Fig. 9). Fastened to each end of the mounting plate -base |03 are side bars |05 (Figs. 2, 4, and 10), said bars being rigidly attached thereto by side bar bolts which fit into side bar bolt holes |06a (Figs. 9 and 10). l',I'hese side bars |05 provide supports for the swing plate shafts |01 (Figs. 2, 4, and 5) and also provide a means for rotating the mounting plate 22 about the mountingsplate shaft 13. Rotation of the swing plate shaft |01 in the side bars |05 is prevented by side bar pin ||0 (Fig. 4). Attached to the swing plate shafts |01 and supported thereon are swing plates ||I (Figs. 4 and 11). In the present embodiment, 20 such plates are supported on/each swing plate shaft. Fastened to each swing plate by means of socket shoulder screws ||2 (Fig. 4) are stocking forms or boards ||3 (Figs. 2 and 6), one for each swing plate. The stocking forms or boards and swing' plates are free to rotate on the swing plate shaft |01 and can assume either a horizontal or vertical (upward) position. The stocking boards in their horizontal position are prevented from assuming a lower position by means of a stop ||4 (Figs. 6 and 11) on the swing plate which comes in contact with the mounting plate base |00. 'I'he stocking boards may be maintained in a vertical position by rotating the stocking boards` about theswing plate shaft |01 until the notch ||5 (Fig. 4) in the swing plate is engaged in the latch IIB, said latch being forced outward into said'notch by a spring ||1 (Figs. 2, 4, and 5) -whichis positioned inthe recess ||1a (Fig. 9) of thef'mbunting plate base |03. Latch retainer |20 holds the latch in place. In the present embodiment of the invention, the latch retainers |20 are rigidly fastened to the mounting plate n base |03 by means of latch retainer screws ||0 (Fig. 4) which t into threaded holes ||0a (Fig. 9).

The mounting plate 22 is locked into position by means of an index pin |2| (Figs. 2 and 5) and index pin guides |22. The bottom face of the mounting plate 22 is provided with index pin stops |23 spaced 120 apart, into which the index pin engages. These holes are so spaced that, when the index pin is engaged in one of the index pin stops, one face of the mounting plate is parallel to the head plate 44, so that the tank may be brought in contact with the face of the mounting plate. In order to rotate the mounting plate 22 about the mounting plate shaft 13, a`downward force is applied to an index pin lever |24. 'I'his disengages the index pin from the index pin stop. The mounting plate is then rotated, usually by means of a force against one of the side bars until the index pin becomes engaged in the next index Vpin stop. A spring |25 maintains the index pin |2| against the lower face of theA mounting plate 22, and when the index pin |2|- is over the index pin stop in the mounting plate, it engages therein and locks the mounting plate so that further rotation will not take place. In order to prevent excessive radiation of heat during the treating operation, the apparatus may be insulated with any` suitable lagging |20.

From the foregoing disclosure, it is believed that the operation of the stocking board setting machine herein described will be readily understandable, but briey, by way of repetition, the following explanation is given: Stockings which preferably have not been subjected to a hot-wet treatment are mounted on stocking forms under tension, the stocking forms being maintained in a vertical position while loading. The loaded stocking forms are then adjusted to a horizontal position. This may be accomplished by applying a downward force to the end of the stocking form, said form being free to rotate about the swing plate shaft |01 (Figs. 2, 4, and 5). The stop ||4 on the swing plate comes in contact with the mounting plate base and positions the stocking boards in substantially a horizontal position.

The mounting plate 22 is then rotated about the mounting plate shaft 'I3 through `120" until the loadedstocking boards are parallel to the center line of the tank. Rotation of the mounting plate is accomplished by releasing the index pin |2| (Figs. 2 and 5) from the index pin stop |23 and applying a force in the direction of rotation to one ofthe .side bars |05 (Figs; 2 and 4). The mounting plate is properly centered by means of the index pin |2| and the next index pin stop.

'I'he tank 2| is next moved horizontally from its extended position, as shown in Fig. 5, to its closed position, as shown in Figs. l and 2. 'Ihe tank is properly positioned when the locking pins 54 are substantially in line with the locking hooks 12., 'I'his movement of the tank is accomplished through the rotation of the handwheel 63 (Figs. 1 and 3), the rotation of the sprockets 31 and 65, the travel of the sprocket chain 1I, and the rotation of the tank,wheels 3|. Control val of time after the setting operation. The high temperatures to which both the forming boards and the stockings are subjected during the setting operation supply suflicient heat to quickly dry the stockings.

In the apparatus shown, 20 stocking forms are mounted on each face of the mounting plate. It is not intended, however, to restrict the presy ent invention to a machine in which 20 stocklever 80 (Figs. 3 and 8) is then pivoted about the pivot pin 11, and this movement causes the locking hooks 'l2 to engage about the locking pins 5I, as hereinbefore described. Final adjustment between the head end of the tank 2| and a face of the mounting plate 22 is made by rotating handwheel 9| (Fig. 4). This causes the tank 2| to slide horizontally along the lockingV bars and makes a tight joint between the gasket I6 and one face of the mounting plate. justment prevents the escape of the setting agent from the tank.

Moisture-containing vapors under superatmospheric pressure are then admitted into the tank and the stockings uniformly wetted and heated. In the preferreclembodimentV of this invention, wet steam is used as the setting agent Other setting agents such, for example, as wet alcohol vapors, etc, may be employed During this treatment. the next section of stocking forms are loaded and dropped into a horizontal position'. After the setting treatment is completed, the setting agent is released from the tank by opening the hand valve 5l (Fig. 2). The tank 2| is then moved from its locked or closed position, as shown in Figs. 1 and 2, to its extended position, as shown in Fig. 5. This adjustment is made by unscrewing handwheel 9| (Fig. 4), disengaging the locking hooks from the locking pins by the Thisnaladremote control mechanism, and rotating handy wheel 63 (Figs. 1 and 3) until the tank takes up the position as shown in Fig. 4.

The mounting plate 22 is then rotated so that the treated stockings are at an angle of 120 with the center line of the tank, and the loaded mounting forms are parallel to the center line of the tank. The tank is again moved into place against the face of the mounting plate, as hereinbefore described, and the operation repeated. 'I'he hosiery which has thus been set is removed from the forming boards and other hosiery placed thereon. Since the set in textile products comprising laments or iibcrs of synthetic linear polyamides is obtained during the hot-wet treatment and not during the drying, as is the case ings may be simultaneously treated, but any apparatus. of the type hereinbefore disclosed wherein the number of stocking forms mounted on one face of the mounting plate is substantially more or less than 20 is considered within the scope of this invention.

Further, while the apparatus has been described with reference to a horizontally movable tank with wheels attached thereto. the invention is not to be limited to this particular embodiment, but any device wherein either the tank or the mounting plate maybe readily adjustable against each other so as to form a closed chamber wherein the products may be treated is to be considered within the limitation of this invention. Furthermore, the tank or the mounting plate may be vertically adjustable and still be within the scope of this invention. 'Ihis is readily apparent from a view of the drawings.

Still further, the locking device for maintaining superatmospheric pressures in the inside of the tank are illustrative only and in no way to be considered as a. limitation upon the present invention. Other means, while not specifically described, are to be considered within the scope of this invention.

While the present embodiment of the invention has been described with particular reference to a hand operated board-setting apparatus, it is not intended to limit the invention thereto.

While the stockingforms or boards described in connection with this invention are solid forms preferably of a metal such as stainless steel and of substantially the shape desired in the finished stocking, they may, if desired, be hollow and heated from the interior by the circulation of hot liquidsor vapors, or heated electrically, thus decreasing the time required to bring the articles to be treated to the proper temperature. Many advantages, however, result from the use of forms made from metal Wire having an outline of the desired shape. (See U. S. Patent No. 2,087,319). The use of wire forms facilitates the passage of the hot vapors to all parts of the stockings, making it possible to place them much closer together during treatment than is possible with solid forms, since, with the latter, it is necessary stocking to stick to the form. Likewise, the movement of parts of the stocking fabric relative to one another are not inhibited by complete con'- tact with a solid surface. This results in a prod- A uct having an improved appearance and a natural and pleasing hand. Finally, wire forms are veryl much cheaper than solid forms because of the ease of their fabrication, reduction in material required, and the reduction of the surface which must be carefully nished. lLikewise, the reduction in weight of the wire forms lends to ease in their manipulation.

gle form for treatment at one time, and stockings so treated have been found to compare favorably in appearance with stockings that are treated singly. The treatment of stockings in this manner possesses several important advantages in that the production of such stockings can bematerially increased, the size of the machine can be made smaller for a given production rate, the initial cost of the machine can be reduced, and floor space can be conserved.

While the apparatus has been described with particular reference to the treating of stockings, it is not intended to limit the invention thereto, but any textile products which are capable of being set when subjected to a hot-wet treatment are considered within the limitations of this invention.

Knit textile products comprising filaments or bers of synthetic linear polyamides can be quickly and efliciently ,set in the apparatus hereinbefore described. Furthermore, wrinkle-free textile products so set will remain free from permanent creases `or wrinkles even though subsequently subjected to the conventional hot-wet treatment necessary in the dyeing operation.

The apparatus is so constructed that alarge number of textile products may be set simultaneously. The floor space required for this apparatus is not great. The time required for treating the products is extremely short, especially when compared with the method formerly employed, that is, when the products were iirst dyed and then set.

Since it is obvious that many changes and modifications can be made in the above-described details without departing from the nature and spirit of the invention, it is to be understood that the invention is not to be limited thereto except as set forth in the appended claims.
